Gulf Shore Lawn and Garden Maintenance provides two general outdoor services: lawn maintenance and garden maintenance. The company charges customers $20.0 per hour for each type of service, but lawn maintenance has higher variable costs ( $12.0 per hour) than garden maintenance (\$6.0 per hour) because of fuel expenses incurred to operate lawn-mowing equipment.
